On Linear Growth in COVID-19 Cases
Computational and Mathematical Biophysics, 2020 We present an elementary model of COVID-19 propagation that makes explicit the connection between testing strategies and rates of transmission and the linear growth in new cases observed in many parts of the world.

Computational and Mathematical Biophysics, 2023 It is now known that early government interventions in pandemic management helps in slowing down the pandemic in the initial phase, during which a conservative basic reproduction number can be maintained.

Dismantling sparse random graphs
, 2007 We consider the number of vertices that must be removed from a graph G in order that the remaining subgraph has no component with more than k vertices.

Global Stability of an SIR Epidemic Model with Delay and General Nonlinear Incidence [PDF]
, 2010 An SIR model with distributed delay and a general incidence function is studied. Conditions are given under which the system exhibits threshold behaviour: the disease-free equilibrium is globally asymptotically stable if R0 \u3c 1 and globally attracting

Computational and Mathematical Biophysics, 2023 Measles is a highly communicable viral infection that mostly affects children aged 5 years and below. Maternal antibodies in neonates help protect them from infectious diseases, including measles. However, maternal antibodies disappear a few months after

A stochastic SICA epidemic model for HIV transmission
, 2018 We propose a stochastic SICA epidemic model for HIV transmission, described by stochastic ordinary differential equations, and discuss its perturbation by environmental white noise.

Cluster formation for multi-strain infections with cross-immunity [PDF]
, 2005 Many infectious diseases exist in several pathogenic variants, or strains, which interact via cross-immunity. It is observed that strains tend to self-organise into groups, or clusters.

, 2016 The main purpose of this work is to investigate the qualitative behavior of an HIV dynamics model with two types of cocirculating target cells. The model takes into account both short-lived and long lived chronically infected cells.

A two-strain ecoepidemic competition model
, 2014 In this paper we consider a competition system in which two diseases spread by contact. We characterize the system behavior, establishing that only some configurations are possible.

OPTIMAL CONTROL OF A TWO TEAMS PREY-PREDATOR INTERACTION MODEL
, 2015 In this paper, a model of two teams of predators interacting with two teams of preys is proposed. The predator teams help each other and so do the prey teams.
